Recommendation to InterBank

After taking into consideration the evaluation of the strength and weaknesses of all three routing strategies, it is recommended that the company should use task switching group routing model due to the fact that it is most commonly and widely used model in the industry as a whole, secondly it would only requires intelligent workforce management system which would assure the effective implementation of the model to gain the favorable and desirable benefits from the model.  It would also save the training cost as it is understandable for the representatives or agents. Also, it would make agents more productive and would be able to handle multiple types of contacts including chat, inbound phone, email etc.
